Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a fastening device for rebar joints in timber structures. Background Technology

[0002] Timber arch structures, especially large-span glued laminated timber arches, are one of the iconic forms of modern timber-framed architecture. Their joint connections, particularly rebar-embedded joints, directly affect the overall safety and stability of the structure. Rebar-embedded technology achieves efficient force transfer by embedding rebars into pre-drilled holes in the timber members and injecting specialized rebar adhesive.

[0003] However, during the on-site installation phase, especially during the critical settling period before the injection and curing of the anchoring adhesive, there is a long-standing technical problem that has not been effectively solved: when connecting two or more sections of wooden arches in the air and inserting anchoring steel bars, due to the self-weight of the components, installation errors, and inadequate temporary fixing measures, it is very easy to cause relative vertical misalignment and in-plane twisting between adjacent wooden arch sections, thereby affecting the load-bearing performance.

[0004] Based on this, the present invention designs a fastening device for rebar joints in wooden structures to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a fastening device for rebar joints in timber structures.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A fastening device for rebar joints in a timber structure includes rebar installation and a bidirectional butt-joint fastening mechanism. The first and second wooden arch sections are connected by a bidirectional docking fastening mechanism; and multiple grooves are provided at the ends of the first and second wooden arch sections that are close to each other; multiple locking threads for installing the bidirectional docking fastening mechanism are also provided on the first and second wooden arch sections. Furthermore, the end where the first and second wooden arch segments meet is designated as the wooden arch splicing surface; Furthermore, the bidirectional fastening mechanism includes a supporting angle steel, a locking nut, a supporting assembly, and a tie rod; the upper and lower supporting assemblies are fitted with supporting angle steel at the ends that are furthest apart; the tie rod is threadedly connected to the locking thread. The lock nut is threaded to both ends of the tie rod. The supporting angle steel is connected to the supporting components; Furthermore, the upper and lower support components are provided with clearance holes for inserting and exiting the tie rods; Furthermore, the diameter of the clearance hole is the same as the diameter of the pull screw; Furthermore, the support assembly includes a support steel plate and a support wooden block; the ends of the upper and lower support steel plates that are far apart are welded and fixed to the support angle steel; Furthermore, the supporting steel plates and supporting wooden blocks are fixedly stacked together, and the supporting wooden blocks are located on the side closer to the first and second wooden arch sections. Furthermore, clearance holes are provided on both the supporting steel plate and the supporting wooden blocks.

[0007] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Before the structural adhesive is injected and cured, the device can actively and accurately apply corrective force to the first and second wooden arch segments, thereby eliminating vertical misalignment and planar distortion, and stably fixing the first and second wooden arch segments in the ideal design position until the structural adhesive is completely cured, thereby fundamentally ensuring the construction quality and final performance of the wooden structure rebar joint. 2. The bidirectional fastening mechanism is recyclable and reusable, and does not involve hydraulic or motor devices. All processed parts are available from the on-site material warehouse, which not only reduces material waste costs, but also reduces equipment rental costs, component processing and maintenance costs, and further reduces construction costs.

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A fastening device for rebar joints in a wooden structure includes rebar 4 and a bidirectional butt fastening mechanism. The first wooden arch section 1 and the second wooden arch section 2 are connected by a two-way docking fastening mechanism; and multiple grooves 9 are opened at the ends of the first wooden arch section 1 and the second wooden arch section 2 that are close to each other; multiple locking threads 10 for installing the two-way docking fastening mechanism are also opened on the first wooden arch section 1 and the second wooden arch section 2. The end where the first wooden arch segment 1 and the second wooden arch segment 2 meet is designated as the wooden arch splicing surface 3. In this invention, the first wooden arch segment 1 and the second wooden arch segment 2 are joined together in a closer direction, and then the reinforcing bar 4 is pre-inserted into the groove 9 of the first wooden arch segment 1 and the second wooden arch segment 2; then structural adhesive is filled into the groove 9 for sealing. At the same time, the two-way fastening mechanism is installed on the first wooden arch section 1 and the second wooden arch section 2 through the locking thread 10. At this time, the two-way fastening mechanism will further pull the first wooden arch section 1 and the second wooden arch section 2 towards the wooden arch splicing surface 3. Before the structural adhesive is injected and cured, the device can actively and precisely apply corrective force to the first wooden arch segment 1 and the second wooden arch segment 2, thereby eliminating vertical misalignment and planar distortion, and stably fixing the first wooden arch segment 1 and the second wooden arch segment 2 in the ideal design position until the structural adhesive is completely cured, thus fundamentally ensuring the construction quality and final performance of the wooden structure rebar joint. Furthermore, the bidirectional fastening mechanism is recyclable and does not involve hydraulic or motor devices. The processed parts are all commonly used parts from the on-site material warehouse, which not only reduces material waste costs, but also reduces equipment rental costs, component processing and maintenance costs, and further reduces construction costs.

[0014] Example 2: In some embodiments, such as Figures 1-4 As shown, in a preferred embodiment of the present invention, the bidirectional docking fastening mechanism includes a supporting angle steel 5, a locking nut 6, a supporting assembly 7, and a tie rod 8; the upper and lower supporting assemblies 7 are provided with clearance holes for the tie rod 8 to pass through and exit; and the supporting angle steel 5 is installed at the far end of the upper and lower supporting assemblies 7; the tie rod 8 is threadedly connected to the locking thread 10. The diameter of the clearance hole is the same as the diameter of the tie rod 8; The locking nut 6 is threaded to both ends of the pull screw 8; The supporting angle steel 5 is connected to the supporting component 7; The supporting angle steel 5 is made of Q235B, and its dimensions can be determined according to the actual cross-sectional dimensions of the wooden arch on site. In this invention, after the first wooden arch section 1 and the second wooden arch section 2 are joined together, a plurality of tie rods 8 are inserted into the clearance holes on the upper support component 7, and the tie rods 8 are screwed in through the locking threads 10 on the first wooden arch section 1 and the second wooden arch section 2 until the tie rods 8 pass through the clearance holes on the lower support component 7. Then, the upper and lower ends of the tie rods 8 are fixed to the support component 7 by the locking nuts 6, thereby fixing the first wooden arch section 1 and the second wooden arch section 2.

[0015] Example 3: In some embodiments, such as Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, the support assembly 7 includes a support steel plate 71 and a support wooden block 72; the support steel plate 71 and the support wooden block 72 are stacked and fixed together; both the support steel plate 71 and the support wooden block 72 are provided with clearance holes; the ends of the upper and lower support steel plates 71 that are far apart are welded and fixed to the support angle steel 5; and the support wooden block 72 is located on the side close to the first wooden arch section 1 and the second wooden arch section 2.

[0016] In this invention, since the supporting steel plate 71 is not bent, the supporting angle steel 5 will increase the bending bearing capacity of the supporting steel plate 71 and improve the supporting force; the supporting wooden pad 72 is used to prevent damage to the surface of the first wooden arch section 1 or the second wooden arch section 2 when the locking nut 6 is screwed into the tie rod 8.
